Disc brake caliper mounting arrangement

Claim 1

In a disc brake assembly having a rotatable member to be braked and a caliper assembly for selectively braking the rotatable member and a nonrotatable mounting bracket on which the caliper assembly is mounted adjacent the rotatable member, a caliper assembly mounting arrangement in which said caliper assembly includes a housing positioned transversely of the rotatable member and having leading and trailing end surfaces, said mounting bracket being positioned adjacent the rotatable member to be braked and having a pair of arms having end surfaces arcuately spaced in a plane adjacent said rotatable member, said caliper housing end surfaces and said mounting bracket arm end surfaces including complementary caliper mounting and guiding surfaces provided with at least one tongue and at least one groove, said tongue-and-groove being in mating relation, and extending transversely of said rotatable member for preventing movement of said caliper assembly radially and arcuately relative to said rotatable member while permitting transverse movement of said caliper assembly relative to said rotatable member, and brake torque transmitting surfaces separate from but contiguous with said tongue and groove and formed on said mounting bracket arm end surfaces and said caliper housing end surfaces adjacent said tongue and groove and in operative abutting engagement for transmitting braking force between said caliper assembly and said mounting bracket.
